Ben 10: Alien Force, Season 1

Grandpa Max:
No, but without the focusing lens, this thing will do a pretty good imitation of a hand grenade. I figured it would take out half a mile.

Highbreed Commander:
You wouldn't dare! You would be destroyed, and your offspring.

Grandpa Max:
Gwen, throw an energy field around you and your boys and... be a good girl.

Ben Tennyson:
(scared) Grandpa Max, no, please!

Grandpa Max:
Sorry, Ben, it's the only way to make sure they can't do to the rest of the world what they did to Ken. You'll have to take it from here. I know you can do it! I believe in you... in all of you. (winks)

Ben Tennyson:
(desperately) Grandpa, NOOOOO!

[Grandpa Max presses the button and everything blows up; Gwen covers the team with an energy dome]

Kevin Levin:
That was, pretty hardcore.

Gwen Tennyson:
He… he saved the whole world.

Ben Tennyson:
Yeah, he did. For now, but I don't think those things are giving up anytime soon!

Gwen Tennyson:
What are you saying?

Ben Tennyson:
I'm saying that it's up for someone to protect this planet. And like it or not... I think it's up to us.
